Glasses Are you tired of reading blurry words and relying on your old eyes? Well at Prada we managed to ďŹ nd a way to ďŹ x that by using our new glasses! Our new glasses are very cheap and require no testing. All you have to do is stop by at our Prada store at Merrick Park. We have been serving our Prada glasses for years now, and we have never received negative feedback!

Your eyes will be shaded from most light waves!!

Sound Waves and Hearing Sound is produced when something vibrates. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound is measured by frequency and intensity. The frequency and intensity is also a part of sound waves and how they work. Sound Waves consist of areas of high and low pressure called compressions and rarefactions. The more compression in the sound causes a higher wavelength. Sound waves are in everything and everywhere, they are in everyday living even though we can’t see them. With sound waves also comes the ability to hear the noise being emulated from the sound. When we hear the sound waves enters the ear canal and causes the eardrum to vibrate. Vibrations pass through the ear and the vibration sets uids to move in the inner ear. It causes nerve impulses to be carried into the brain by the auditory nerve and these impulses are converted into sound.

Mechanical Waves

A wave can be described as a disturbance which travels through a medium from one location to another location. So when speaking about mechanical waves, there is a similarity between the two. A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A medium is a disturbance travelling through matter or space, transferring energy from one place to another.

Mechanical waves, such a sound waves and water waves, carry energy through a medium. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum, which ďŹ ts under the mechanical waves deďŹ nition. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.The high point of a transverse wave is a called the crest, and the low point is called the trough.The distance between successive crests or troughs is called the wavelength. The height of a wave is the amplitude. How many crests or troughs pass a speciďŹ c point during a unit of time is called the frequency.

Mechanical Waves (continued) An example of a mehanical wave in action is a slinky. If the slinky gets stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the ďŹ rst coil up and down. Energy will begin to be transported through the slinky from left to right. The individual coils of the medium will be displaced upwards and downwards.

Light Waves and Sight Believe it or not if there is no light than there is not sight. Apart from looking directly at a light source, most of what we see is as a result of the process of reection. Light in a vacuum travels at a constant speed of 300,000 km/s. Its speed in media like air, water and glass is slightly slower. It is this change of speed that lies behind the phenomenon known as refraction.We are able to see because light from an object can move through space and reach our eyes. During the day, the sun generates light to be able to live on Earth. The cornia is a clear covering on the surface of an eye that focuses light as it enters the eye. The Lens inside the eye further focuses light

Electromagnetic Waves Electromagnetic radiation is a way that energy travels through space. Some forms of electromagnetic radiation are X-rays, the heat from a fire, and the light from the sun. The waves in the ocean are the same as light and sound waves, they both mean a disturbance in a particular physical field, resulting in a vibration.

Electromagnetic waves are similar to ocean waves, except electromagnetic waves repeatedly move back and forth in a perpendicular motion. One of the electromagnetic waves is an oscillating magnetic field and the other is an oscillating electric field.

Scientists put electromagnetic radiation towards atoms, matter, and elements to see the outcome of the substance. Electromagnetic radiation helps decipher the molecules structure, and the type of chemical bond it contains.

The electromagnetic spectrum is the classifications of electromagnetic waves according to their wavelengths and frequencies.

The visible spectrum makes up a small portion of the radiation that exists. To the right of the visible spectrum, the matter that is classified has a smaller amount of radiation. To the left, the matter that is classified has a larger amount of radiation. The left contains ultraviolet (UV) light, X-rays, and Gamma rays. These three things are harmful to one’s health and can potentially kill. It is for this reason that people wear sunblock at the beach, to block the UV rays from the sun, and why an X-ray technician will place a lead cover over us, in order to prevent the X-rays from penetrating anything other than the area of our body being imaged. Gamma rays, being the highest in frequency and energy, are impossible to be in contact with the people living on earth because our atmosphere absorbs gamma rays from outer space.

Wave Facts The highest point of a wave is known as crest.

The lowest point is known as trough.

While electric charges can create electric fields, magnetic fields can also create electric fields

Magnetic fields are created by magnets.

Every time you change a magnetic field, you create an electric field.

“Numbers in the News�

- As of 2012, more than 39 million people were blind.

- In the U.S. there is approximately 1 million people who are deaf.

- Dalmatians are the dog breed who are most at risk of deafness.

- Star-nosed moles are born blind because they live underground meaning that they do not need eyesight.

- 8 million people who are deaf are over the age of 60
